Brent rises 2.2% to $111 after Iran reports 7 tankers damaged in Strait of Hormuz
Crude hit its highest level since May on Oct. 22 after Iran's state television reported seven oil tankers caught fire and were damaged in the Strait of Hormuz. Brent rose 2.2% to $111.19, the top end of the $97 to $112 band it has run through all month. If the report holds up, it would be the most vessels damaged in the waterway in a single day since the Iran war started Feb. 28. For anyone buying wholesale product, that $111 print sets the floor your rack prices get built on.
Joliet upset
Midwest gas prices jumped after an operational upset at the Joliet refinery, per Crain's Chicago Business. That one is close to home. A single large plant hiccuping in the middle of the country tightens supply across a wide buying area fast, and jobbers in that footprint may see spot and rack numbers move before the national average catches up. Watch your supplier allocations if you pull anywhere near PADD 2.
Summer run rates
US refiners ran harder than normal all year. EIA put refinery utilization above 95% of capacity from May through September, the highest for those months since 1998 and well over the 92% average since 1991. Tight global product supplies drove it, diesel most of all, with margins fat enough to keep every available unit turning. Valero even set a record for Venezuelan crude runs, per BNamericas.
High utilization is good for keeping product on the street, but it leaves little slack. When plants run flat out and one stumbles, like Joliet, there is no easy spare barrel to cover the gap, which is part of why a regional upset bites harder this year.
Hormuz and the barrels
India's Middle East crude imports jumped 32% in September to 2.8 million bpd, the highest since February, and Middle Eastern oil made up 54% of its intake, per Reuters vessel data. Almost all of that moves through Hormuz. The reason a tanker fire there matters to a US operator is simple: the strait carries a big share of the world's seaborne crude, so damage there competes for the same barrels your refiners buy and pushes the benchmark your rack prices track.
What to watch
Whether Iran's seven-tanker report gets verified, and how many vessels are actually out of service, could decide if Brent holds its gains or eases back into its October range. Crude could soften if the strait stays open and traffic normalizes. On the ground, watch how long Joliet stays off and whether Midwest racks keep climbing. Diesel margins are the other tell: as long as they stay wide, refiners keep running hard and product stays available, thin cushion and all.
